What are the characteristics of different memory slots?

Different memory slots vary primarily in their type, size, and compatibility with specific memory modules. Common types include DIMM (for desktops), SO-DIMM (for laptops), and LRDIMM (for servers), each designed for different form factors and applications. Additionally, slots may support various memory technologies like DDR, DDR2, DDR3, DDR4, and DDR5, which differ in speed, bandwidth, and power consumption. The number of pins and the arrangement of the notch also determine compatibility, ensuring that only the appropriate memory modules can be installed in each slot.
